Weird hollow noise over bumps from new B4 suspension?

mclovin69x · 04-25-2024, 03:26 PM

Replaced the stock adaptive suspension in my car with non adaptive Bilstein B4 shocks. Kept same old springs but replaced bump stops and dust sleeves.

Now there’s this weird hollow noise going over bumps.

Everything else with suspension looks good any idea what it can be?

Could be just the way the car sounds now, with all the modifications done.

This sounds normal for bumpy roads?

I wouldn’t say so.. this noise is relatively new. I think it started after I installed Bilstein B4. I am going to Koni Special Active with Eibach Pro Kit to see if it fixes it.

If it doesn’t, then I’ll get rid of the camber plates to see if that helps
